Filter by:Physical activity is the most beneficial and cost-effective treatment for Veterans with PAD, however, issues with oxygen delivery and utilization dramatically impair exercise compliance. The cause of these oxygen delivery and utilization impairments is likely increased oxidative stress and inflammation. The proposed project will comprehensively examine the novel strategy of Nuclear Factor Erythroid-2-like 2 (Nrf2) activation using PB125, aimed at diminishing oxidative stress and inflammation, and thereby lessening the negative impacts of the disease. This therapeutic will be evaluated in isolation and in combination with exercise rehabilitation to determine if there is a complimentary benefit. The ultimate goal is to provide insight into a potential novel therapeutic treatment for this disease, therefore, improving exercise tolerance and quality of life in this growing population.
Prevalence of diabetes mellitus (DM) is increasing rapidly, with patient numbers projected to rise to 643 million by 2030. As a consequence of diabetes-related atherosclerosis, peripheral arterial disease (PAD) and in particular medial arterial calcification (MAC) can occur. The accurate identification of PAD by bedside tests is extremely important in patients with diabetes and foot ulceration, in order to reduce delayed wound healing, prevent lower limb amputation and eventually reduce mortality. However, as shown in previous systematic reviews, the performance of current bedside tests is not reliable in excluding PAD in diabetic patients.1,2 Moreover, the methodological quality of the conducted studies is generally poor. Therefore, more reliable and prospective data is required. Also alternative bedside tests need to be investigated. As an example, the ACCmax (a new doppler derived parameter) could be particularly promising in this patient group.
The aim of this study is to investigate the effect of different treatment strategies on mitochondrial function and to correlate in-vitro results to findings from in-vivo measurements of mitochondrial function. The authors hypothesize that interventional revascularization and therefore the restoration of blood and oxygen supply is more relevant to mitochondrial function compared to the effect of exercise training.
This study aims to evaluate the comparative risk of dementia/Alzheimer's disease onset between patients treated with medications that target specific metabolic pathways and patients treated with alternative medications for the same indication.
This is a study of biomarkers obtained from prospectively collected subject samples and their correlation with cardiovascular and metabolic diseases. The purpose of this initiative is to develop an enduring tool to allow for collaborative research between clinicians at Cleveland Clinic Main Campus and basic scientists at the Lerner Research Institute. This collaboration will allow resources to be available to clinical and basic researchers alike. This tool will enable research of vascular disease in the Vascular Lab and will leverage this valuable asset to the fullest extent to allow for interdepartmental collaboration.
This trial was a prospective, multicenter, single-group design. To undergo endovascular treatment of lower extremity arteriosclerosis obliterans After the subjects were selected and enrolled, the surgeons used the endovascular interventional surgical instrument control system developed by Shanghai Aopeng Medical Technology Co., Ltd. and the consumables of the endovascular interventional surgical instrument control system for the interventional hand Instrumentation (guide wire, catheter, stent, balloon) for remote delivery, manipulation, and withdrawal
The BEET PAD Trial is a multi-centered double-blind randomized clinical trial designed to determine whether beetroot juice, compared to placebo, improves six-minute walk distance at four month follow-up in people with lower extremity peripheral artery disease (PAD). Investigators hypothesize that by simultaneously increasing lower extremity perfusion, gastrocnemius muscle mitochondrial activity, and myofiber health and regeneration, beetroot juice will significantly improve walking performance in people with PAD. The primary aim is to determine whether beetroot juice significantly improves six-minute walk distance at 4-month follow-up in people with PAD, compared to placebo. Preliminary evidence suggests that beetroot juice has both acute and chronic effects on walking performance in PAD. The primary outcome will measure the combined acute and chronic effect of beetroot juice (i.e. the maximal effect) on change in 6-minute walk at 4-month follow-up. In secondary aims, investigators will distinguish between acute and chronic effects of beetroot juice on six-minute walk and delineate biologic pathways by which beetroot juice improves walking performance in PAD, by measuring change in gastrocnemius muscle perfusion (MRI arterial spin labeling) and gastrocnemius muscle health. The trial will assess the durability of beetroot juice effects on six-minute walk. Nitrate in beetroot juice is metabolized to nitrite and subsequently to NO, attaining peak nitrite levels 2.5 hours after ingestion. The trial will determine whether a higher peak or a greater increase in plasma nitrite at 2.5 hours after beetroot juice consumption at baseline has a greater effect on six-minute walk at 4-month follow-up, compared to a lower peak or a smaller increase, respectively.
The Inperia Advance Carbostent™ is a CE-marked infra-popliteal stent for treatment of infra-popliteal artery stenosis. The aim of this post-market retrospective study protocl P32203 is to collect clinical data of patients treated with Inperia Advance for the treatment of infra-popliteal artery stenosis in routine clinical practice. In order to obtain long-term follow-up data, the data collection will be limited to patients that have been treated with the device at least 12 months prior to the study start.
This study is a multicenter observational study designed to evaluate the the effectiveness and safety of drug-coated balloon (DCB) angioplasty for below the knee arterial lesions in patients critical with Limb Threatening Ischemia (CLTI).
The aim of the study is to analyze the applicability (usability) of a tele-health service as part of a potential disease management program for patients with peripheral arterial disease. The following investigations will be conducted as part of the usability study. In the context of a tele-health service, knowledge, physical condition (including walking distance) will be documented during face-to-face and televisits, dislocated supervised gait training and education will be provided, and satisfaction with the tele-health service will be evaluated.
